The K&F Concept 43mm UV Filter KF01.1419 is a compact lens filter designed to reduce ultraviolet light while adding an extra layer of protection to the front element of a compatible lens. Part of K&F Concept’s Classic Series, it combines Japanese optical glass with a slim aluminum frame and multi-coated surfaces.
With its 43mm filter diameter, the KF01.1419 fits lenses that use a 43mm front filter thread. Therefore, check the filter-thread size marked on your lens before purchasing.
UV Filtration for Clearer Outdoor Images
The K&F Concept KF01.1419 filters ultraviolet light that can contribute to haze in outdoor scenes. This can be useful when photographing mountains, landscapes, water, and other distant subjects where atmospheric haze is more noticeable.
At the same time, the filter adds minimal complexity to your setup. Once installed, it stays on the lens while you shoot, giving you a convenient layer of protection without requiring constant adjustment.
Japanese Optical Glass
The filter uses Japanese optical glass, helping maintain image clarity while providing UV filtration. The glass also adds a physical barrier in front of the lens, helping protect the front element from everyday dust, fingerprints, and minor contact.
For photographers who regularly work outdoors, this extra layer can be particularly useful because cleaning or replacing a filter is generally easier than dealing directly with the front element of the lens.
Multi-Coated Surface
The KF01.1419 features a multi-coated optical surface designed to reduce reflections and help maintain good light transmission. The coating also helps limit flare and glare that can occur when shooting in challenging lighting conditions.
As a result, you can keep the filter installed for everyday photography without adding unnecessary bulk to your camera setup.
Slim 3.3mm Aluminum Frame
One of the key advantages of this filter is its slim 3.3mm frame. The thin profile helps reduce the possibility of dark corners when using wider-angle lenses.
The frame uses lightweight aluminum construction, so it adds very little weight to the front of the lens. This makes the KF01.1419 a practical option for travel, landscape, street, and everyday photography.
Easy Installation
The filter uses a standard threaded design for compatible 43mm lenses. Simply screw it onto the front filter thread of your lens and you’re ready to shoot.
Because the filter remains easy to remove, you can also take it off whenever you need to use another filter, such as a CPL or ND filter.
Lens Protection for Everyday Photography
Besides UV filtration, the K&F Concept 43mm UV Filter KF01.1419 provides a convenient protective layer in front of the lens. It can help shield the front element from:
- Dust
- Fingerprints
- Dirt
- Minor scratches
- Accidental contact
- Outdoor debris
This makes it particularly useful for photographers who want additional protection during regular shooting.
Designed for Wide-Angle Use
The slim frame makes the KF01.1419 suitable for use with compatible wide-angle lenses where thicker filter frames can potentially introduce vignetting.
Therefore, you can add UV protection without unnecessarily increasing the thickness around the front of your lens.
